IMPROVED CHAIR.

Specitication forming part of Letters Pa To all whom fit may concern Be it known that I, JACOB UNGERER, of Brooklyn, ,Kings county, and State of New York, haveinvented a new and useful Improvement in Chairs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a vertical section of this invention. Fig. 2 is an inverted plan of the same.

Similar letters of reference indicate like parts.

This invention consists in a chaicseat made of metal, wire, or strips of sheet metal, braided or otherwise interlaced, as may be desired, in such a manner that a strong, cheap, and durable seat is obtained.

It consists, also,in combining with the metallic seat a metal frame, which is secured in the frame ot' the chair, and to which the ends ofthe wires composing the seat are fastened, by soldering or any other suitable means, in such a manner that a firm and durable connection between the metallic seat and the frame ct' the chair can be eit'eeted with little trouble or loss of time.

It consists, finally, in supporting the seat by a series of springs and elastic pads, in such a manner that the strain on said seat is equalized and the seat is prevented from sagging down.

A represents a chair-seat made of metal Wire'or strips of sheet metal, which are braided or interlaced in any desirable man- 11er, and which may be protected by paint or tent No. 58,9 I '7, dated October 16, 18H6.

other means to prevent corrosion. The ends of the wires or strings composing my scatare secured to a metal frame, B, either by solder or any other suitable means; and each metal frame is secured in the frame O of the chair by screws, nails, or any other suitable means. By the use ot' this metal frame, the operation of securing the seat to the chair frame is greatly facilitated, and the seat is strengthened and brought in such a shape that the same can be bought in the market independent of the chair-frame.

Under the seat extends a series of springs, l), which support a number of sprngpads, a, bearing on the under surface ot' the seat. By the combined action of these springs and spring-pads the strain which the seat has to sustaiu,ifa person sits down on it, is equalized, and the seat retains its level, being prevented from sagging down.

My chair-seat is strong, durable, and easily made. It can be connected to the chair-trame, so that it strengthens the same instead ot' being a source of weakness, and by the springs and spring-padsit is enabled toretain its level shape for a long time.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the metal frame B with the metallic seat A, substantially as und for the purpose described.

2. The springs and springpads a, in combination with the seat A and chair-frame C, and operating substantially as and for the purpose set forth.
